Three RCTs showed that rubber band ligation was better than injection sclerotherapy in a variety of outcomes (pain, repeat treatment, prolapse, bleeding) in persons with mainly second-degree hemorrhoids; however, rubber band ligation was associated with more immediate adverse effects.
Edema is the medical term for swelling. Body parts swell from injury or inflammation. It can affect a small area or the entire body. Medications, infections, pregnancy, and many other medical problems can cause edema. Edema happens when your small blood vessels become leaky and release fluid into nearby tissues.
Many of the events involved in inflammation are increased by estrogen, and decreased by vitamin E. Estrogen causes capillaries to become leaky; vitamin E does the opposite. Estrogen increases platelet aggregation, and decreases a factor that inhibits platelet aggregation; vitamin E does the opposite.
